have a Macgregor 22 with a tohatsu 6hp sailpro that has a flushing port. boat is in a slip. With the motor bracket in the up position the impeller water intake is below water, so when I flush the motor, I have to tilt it, any problem with this? It does run while tilted, just seems unconventional and not sure if the engine oil gets picked up. I like to run the carb empty while flushing, so not sure if this can be achieved if tilted.

My neighbor had a small Honda, which he would attach a hose to the shaft where the water intake was. He turned on the water, and it flushed the water lines with fresh water. He would run the fuel out of the carburetor at the same time till the engine died. I am guessing that if you had a way of running fresh water into the shaft, it could sit in the water while the engine ran (no tilt). Then you could apply the tilt and turn off the hose.

Something like this.

Can you put a 5 gallon bucket in the water with the motor shaft inside of it? Then place a hose inside the bucket to keep it filled with with fresh water While flushing?

I think muffs are difficult to use with such a small outboard. I'd opt for the flush kit. I had a Tohatsu 4hp for a decade and never flushed it, but that was freshwater. I did run it in a 55 gallon drum, which eventually I was advised by my family to get rid of because they said it looked like something a serial killer would keep in their backyard.

That is exactly why you should have kept it.
